We received the results of the sleep study that was done on April 4th. They say she had 21 central apneas during the night. This is something they are concerned about and want to do another study soon using oxygen to sleep to see if that makes a difference. I am not sure about using oxygen. Some of the things we have read say that they become dependent on the oxygen??? We will see. It is disappointing to hear this because she seems to be doing well right now. I guess we will see what this next study shows.
